Definitions

• ABSTRACT This invention relates to acaricides containing one or more derivatives, wherein the derivatives are expressed by the formula S(O)nR1 R2 where X represents a halogen, a lower alkyl group or a lower alkoxy group, R represents a lower saturated alkyl group or an unsaturated alkyl group R represents hydrogen, a halogen, a lower alkyl group, a lower alkoxy group, a lower alkyl thio group, a nitro group or a trifluoromethyl group, and n is any one of the integers O, 1 and 2.
• Compounds of formula (I) can be obtained by condensing in the presence of an alkaline compound or an acid-binding agent a compound expressed by the following formula (II) where X, R, and n have the same meaning as defined hereinbefore, and a compound expressed by the following formula (III) (III) 3-n-propylthio-4- 3-ethylthio-4- 3-allylthio-4- 3-n-propylsulfinyl-4- 3-n-propylsulfi- 3 -n-propylsulfo- 3-n-propylsulfonyl-4-propylphenol, 3-npropylsulfonyl-4-methoxyphenol, 3-ethylsulfonyl-4-methoxyphenol, 3-npropylsulfonyl-4-ethoxyphenol, etc.

• the compounds of formula (II) have been previously converted into a sodium or potassium salt thereof, it is, of course, unnecessary to use the acid-binding agent.
• the reaction can be smoothly conducted by using an aprotic polar solvent such as dimethyl sulfoxide, dimethylformamide, dimethyl acetoamide, or diethylglycol diethyl ether, or a protic solvent such as diethylene glycol monoethyl ether, but the use of these solvents is not essentially required.

• the reaction temperature may be varied depending on the kinds of compounds and solvent used, but is within a range of 100 to 200C, preferably 120 to 180C. In this range, the reaction proceeds smoothly, and 90% of the starting compounds are converted into the required reaction products after about 4 hours. However, it may be necessary to react the mixture, for example, for about 6 hours under certain reaction conditions with certain particular kinds of the compound of formula (ll). After completion of the reaction (or after distillation of any solvent used, following the completion of the reaction), the reaction mixture is cooled to a temperature below 100C, and a suitable amount of water is added thereto to separate the desired oil therefrom. Then, the separated oil is extracted by the use of an organic solvent.
